Description and Introduction

MicroPower Voltage Reference Diodes The LM385B is a micropower voltage reference diode manufactured by Texas Instruments. Below are its specifications, descriptions, and features based on factual information:  

### **Manufacturer:** Texas Instruments  
### **Part Number:** LM385B  

### **Description:**  
The LM385B is a precision, low-power voltage reference diode designed for use in a variety of applications requiring stable voltage references. It operates at very low currents, making it suitable for battery-powered and energy-efficient systems.  

### **Key Features:**  
- **Voltage Options:** Available in 1.235V (LM385B-1.2) and 2.5V (LM385B-2.5) fixed reference voltages.  
- **Low Operating Current:** Typically 10µA to 20µA, making it ideal for low-power applications.  
- **High Accuracy:** Tight initial tolerance (e.g., ±1% for LM385B-1.2, ±2% for LM385B-2.5).  
- **Wide Operating Current Range:** 10µA to 20mA.  
- **Low Dynamic Impedance:** Ensures stable voltage regulation.  
- **Temperature Stability:** Low temperature coefficient (typically 20ppm/°C for LM385B-1.2).  
- **Wide Operating Temperature Range:** -40°C to +85°C.  

### **Applications:**  
- Battery-powered devices  
- Portable instrumentation  
- Voltage regulators  
- Analog-to-digital converters (ADCs)  
- Digital-to-analog converters (DACs)  

### **Package Options:**  
- TO-92 (3-pin)  
- SOIC-8 (surface mount)  

This information is based on the manufacturer's datasheet and technical documentation.
